Device for ordering at dining table

Abstract

A device for ordering at a dining table, which is applied in a restaurant or an eatery, can be used to transmit menu messages, browse a menu status, pay the bill and surf the Internet. The device has a program control module used for performing a menu process, a transaction process and a digital transmission program. A first displayer is connected with the program control module to show a menu, a transaction status or a digital message. A first interface is connected with the program control module for connecting at least an external device. A first radio module is connected with the program control module for connecting the program control module with the remote host for data transferring.
